Queen's jubilees chronicle changing times in Britain

A visitor wearing a tshirt picturing Britain's Queen Elizabeth II, arrives at The Mall, in London, on June 1, 2022.

Queen Elizabeth II's Platinum Jubilee celebrations will be only the ninth such celebration by a British monarch since King George III in 1809.

Both she and Queen Victoria, who ruled from 1837 to 1901, have had silver, golden and diamond events to mark their 25th, 50th and 60th years as monarch.

But Elizabeth is the only one to celebrate her 70th year on the throne.
